Oregon Arrest and Race Analysis
Russell_Corey
December 14, 2022
Intro
This project investigates racial disparities in police arrests in Oregon utilizing open source data. The source code and data for this project is hosted at Github
Data
The two data sources used are the “Uniform Crime Reporting” Offenses data and the Oregon 2020 Census data from Portland University.
Crime Data
The crime reporting data set is accessible directly from
https://www.oregon.gov/osp/Pages/Uniform-Crime-Reporting-Data.aspx
Population Data
The Oregon census data can be found at the website
Methodology
First arrest data is loaded with OpenData-Arrests.r which reads in the corresponding data source data/OpenData-Arrests.r. The arrests are then grouped by police agency and race.
Next, census data is loaded using City_data_2020.r which reads data/City_data_2020.xlsx.
Then using Arrests_and_Census.r and the table data/agencies_cities_map_cities_only.csv the names of police departments are joined to the city names in City_data_2020. Only cities with corresponding police departments are kept.
Then using the race demographics in the census data, the percentage of each race population is calculated for each city. Then the percentage of each police department’s arrests are for each race. Then the percentage of arrests for each race is subtracted by the corresponding race population percentage for each police department/city.

Correlation Analysis
We want to inspect potential correlations between racial population density and arrest biases. First we will inspect the data to see what type of correlations we may want to perform.
From the QQ plots we see most of the data series are not normally distributed. See Appendix A3 for all the plots. So we will perform a Spearman’s correlation since the data does not meet the assumptions of the Pearson’s correlation test.
